DETAILED DESCRIPTION

A light detection and ranging (LiDAR) sensor measures distance by illuminating a target with a laser light. The laser light is reflected back to the LiDAR, providing information about potential obstacles and the surrounding environment of the autonomous vehicle.

Mirror 140 is coupled to the bottom housing platform 130 via the mirror bracket 132. The integration of the mirror 140 on the LiDAR mirror assembly is an advantageous feature at least because the mirror 140 can replace the vehicle's stock mirror with similar dimension or location on the vehicle. As shown in FIGS. 8 and 9 , the LiDAR mirror assembly is mounted on a hood of the vehicle so that the mirror 140 is on the side that faces the driver or the vehicle's cab so that a driver can see an image of an area reflected by the mirror 140. In FIG. 1 , the mirror 140 is located on a side surface of the housing. For example, the mirror 140 is located adjacent to a side surface of the top housing enclosure 160 and the second bottom housing enclosure 134 b or the bottom housing platform 130. Mirror 140 may be coupled to the bottom housing platform 130 at a location distal to the base plate 110 and away from the opening in the housing that includes the sensor 150.

In some embodiments, the front side of top housing enclosure 160 faces toward the vehicle cabin and the back side of top housing enclosure 160 faces in the opposite direction.

The sensor 150 is coupled to the bottom platform at a location where at least some surface of the sensor 150 exposed through the opening. The at least some surface of the sensor 150 is exposed to the environment via the opening so that sensor can transmit light pulses and measure reflected light that bounces off of one or more objects in an environment where the vehicle is being driven. The at least some exposed surface of the sensor is recessed from an edge of the top housing enclosure 160 and the bottom housing platform 130 at a distal end relative to the base plate 110.

The distal end of the top housing enclosure 560 relative to the base plate can have a semi-circular shape. The rounded end farthest away from the base plate 510 allows the opening to be seen from both the front side of the top housing enclosure 560 and back side of the top housing enclosure 560. The rounded end farthest away from the base plate 510 defines the contour of the opening.

Top housing enclosure 560 may be coupled to bottom housing platform 530. In some embodiments, top housing enclosure 560 may be coupled to first bottom housing enclosures 534 a or second bottom housing enclosure 534 b. Top housing enclosure 560 may include holes that pass through a portion of top housing enclosure 560. The holes may be used for a mounting fixture to attach to the bottom housing platform 530 or the first bottom housing enclosure 534 a or the second bottom housing enclosure 534 b.

FIG. 10 shows an exemplary LiDAR housing with an LED.

LED 164 is coupled to top housing enclosure 160. LED 164 may be an array of LEDs. LED 164 may be a solid-state semiconductor device that emits light. In some embodiments, the LED may be replaced with a more conventional light source such as incandescent bulbs or fluorescent lamps. Many of the embodiments described include the LED 164 attached to the LiDAR mirror assembly 100. But LED 164 may be attached to any other portion of semi-trailer truck 805.

LED 164 is representative of an autonomous mode of semi-trailer truck 805. LED 164 may present a status indicator that represents the mode of operation of semi-trailer truck 805. Modes of operation include autonomous, semi-autonomous, or human-controlled. Other modes of operation may be representative of the level of autonomy of the vehicle. Other modes of operation may correspond to the five levels of autonomous driving L0-L5: Level 0 (L0) corresponds to no automation; Level 1 (L1) corresponds to driver assistance systems; Level 2 (L2) corresponds to partial automation driving where systems can take control; Level 3 (L3) corresponds to high autonomous driving in which the driver may disengage from driving for extended periods of time; Level 4 (L4) corresponds to fully automated driving where the vehicle drives independently most of the time; and Level 5 (L5) corresponds to a fully autonomous vehicle.

LED 164 may represent an autonomous mode of semi-trailer truck 805 by presenting a status indicator. A status indicator may be a color where each color corresponds to a mode of operation. A status indicator may be a sound where each sound corresponds to a mode of operation. A status indicator may be a pattern of light corresponding to a mode of operation. The pattern of light may power LED 164 on and off at a particular rhythm. In a plurality of LEDs, the pattern of light may be displayed by turning on or off multiple LEDs either simultaneously or sequentially. A status indicator may be an intensity of light where each intensity corresponds to a mode of operation. Where LED 165 is an array of LEDs, the position of the powered LED corresponds to a mode of operation.

LED 164 may emit a light in the visible spectrum. Alternatively, LED 164 may emit an infrared light or ultraviolet light. Light emitted from LED 164 that falls outside the range of wavelengths visible to the human eye may communicate the status of the autonomous vehicle. In some embodiments, the light emitted from LED 164 may be modulated to communicate a status of the autonomous vehicle.

LED 164 may be placed outside the field of view of the cabin of the vehicle. LED 164 may be placed on the back side of the LiDAR mirror assembly 100. A driver inside the cabin of the vehicle will not be distracted by LED 164 by having the LED emit light away from the driver.
